6 FAQs about [Lithium Battery Thermal Conductive Materials Co Ltd ]

What is thermal management technology for lithium-ion batteries based on PCMS?

For example, thermal management technology for lithium-ion batteries based on PCMs is widely applied in lithium-ion battery thermal management systems (BTMS) as it eliminates the need for complex and expensive components and does not consume the energy of the lithium-ion battery itself [, , ].

Which CPCM has the highest thermal conductivity in Li-ion batteries?

In 2022, Chen et al. prepared seven CPCMs by adding different ratios of SiC/SiO 2 using PA and EG as raw materials. The results showed that the prepared CPCMs had the highest thermal conductivity when the content of both EG and SiC was 10 %, which could meet the requirements of thermal management of Li-ion batteries.

How to reduce the thermal runaway risk of lithium-ion batteries?

Multiple requests from the same IP address are counted as one view. To reduce the thermal runaway risk of lithium-ion batteries, a good thermal management system is critically required. As phase change materials can absorb a lot of heat without the need for extra equipment, they are employed in the thermal management of batteries.

How effective is thermal management for lithium ion batteries?

The results showed that it exhibited good thermal management performance for Li-ion batteries; and it showed good impact absorption performance, which played a good role in protecting lithium batteries from short circuits.

What is the maximum temperature of a lithium ion battery?

It is found that the maximum temperature of the LIB is as high as 81.6 °C without the addition of CPCMs. At this time, the long-time usage of LIBs already has a certain risk of thermal runaway. After adding the CPCMs, the maximum temperature of the battery can be reduced to 63.6 °C.

What materials are used in thermal conductive materials?

Thermally conductive materials with porous materials [e.g., aluminum foam, copper foam, nickel foam, and expanded graphite (EG)] and nanoadditives (e.g., graphene, multiwalled carbon nanotubes, and carbon fibers) are added to the PCM to improve thermal conductivity [20, 21, 22, 23, 24].
